2026 Premium Proxy & Dedicated Line Buying Guide: IEPL Architecture & Protocol Analysis

@ Review

Modern proxy services exhibit drastic performance variations based on upstream transit infrastructure. Understanding the difference between public transit and dedicated private circuits is essential for making an informed choice.

1. Dedicated Lines (IEPL) vs Public Transit

Standard public transit routes frequently suffer from severe congestion during peak evening hours, causing packet loss rates exceeding 30%. In contrast, genuine IEPL (International Ethernet Private Line) bypasses public internet gateways through private fiber links, delivering millisecond consistency and near-zero jitter.
